A first synchronization request (1051) is communicated from the client-computing device (110) to the metadata server (123). In the present example, the client's update cache will not contain any updates, given that this is the first execution of the method. Thus, the first synchronization request 1051 does not contain an identifier for a cached update. In response to receiving a synchronization request, as shown in block (1052), the metadata server (123) determines if the synchronization request contains at least one update identifier. If it is determined that the synchronization request does not include an update identifier, the metadata server (123) responds by selecting first level updates for communication to the client computing device (110). As described above, first level updates may include any updates that do not have a prerequisite identifying other updates. |
